This strong anion-exchange medium is designed for downstream purification of proteins, nucleic acids, and peptides. It uses a highly crosslinked agarose matrix functionalized with quaternary ammonium groups. The spherical gel structure supports high flow with low backpressure. High binding capacity supports productive capture and intermediate purification operations. Low nonspecific adsorption contributes to product recovery and process consistency. The medium provides chemical and mechanical stability during repeated processing. A broad cleaning-in-place pH range supports regeneration between purification cycles. The medium can be scaled from process development to larger manufacturing columns. Steam exposure at the stated conditions is supported for compatible process requirements.
